Call for Price

The TST01G-D is a 1Gbps 1000BASE-T SFP (RJ-45) copper transceiver module that delivers reliable Gigabit Ethernet connectivity over standard Cat5/6 cabling up to 100 m. Hot-pluggable and IEEE-802.3 compliant, the TST01G-D is a cost-effective option for adding RJ-45 uplinks to SFP ports on switches and routers, enabling flexible deployments and multi-vendor interoperability. Ideal for data centers, enterprise access layers, and branch office links where copper 1G uplinks are required

TST01G-D — 1Gbps 1000BASE-T RJ-45 SFP Copper Transceiver

The TST01G-D is a high-performance 1000BASE-T SFP copper transceiver designed to provide flexible Gigabit Ethernet uplinks using existing copper cabling infrastructure. Engineered for compatibility and easy deployment, the module converts an SFP slot into a standard RJ-45 1GbE port — enabling switches, routers, and network appliances to use copper connections without occupying fixed RJ-45 ports.

Key Benefits

Flexible uplink options: Add copper Gigabit links to devices with SFP ports for short-haul connectivity.
Cost effective: Uses widely available Cat5/6 cabling up to 100 meters, avoiding fiber transceivers when appropriate
Hot-pluggable and standards compliant: Conforms to IEEE 802.3/802.3ab SFP and 1000BASE-T specifications for broad interoperability with many vendors’ equipment.
